WEBVTT 00:00:11.720 --> 00:00:15.060 Breaking free from the chains of the past Where 00:00:15.060 --> 00:00:18.820 truth moves faster than a Holstein calf No law 00:00:18.820 --> 00:00:21.660 waiting on some printed page We're charting new 00:00:21.660 --> 00:00:25.300 ground in the digital age From genomic codes 00:00:25.300 --> 00:00:29.120 to robot facts We cut through the noise, no hold 00:00:29.280 --> 00:00:32.460 them back not your daddy's dairy news tonight 00:00:32.460 --> 00:01:03.530 we're sparking Welcome back to the Bullvine Podcast, 00:01:03.770 --> 00:01:06.049 where we cut through dairy industry noise to 00:01:06.049 --> 00:01:08.590 get you the insights that actually matter for 00:01:08.590 --> 00:01:11.650 your operation. And today we're diving deep into 00:01:11.650 --> 00:01:14.510 a feature piece about what we're calling rumen 00:01:14.510 --> 00:01:17.750 gold. This is an intensive look at recent research 00:01:17.750 --> 00:01:22.090 and field data on the rumen microbiome and specifically 00:01:22.090 --> 00:01:24.969 how much profit we are accidentally leaving on 00:01:24.969 --> 00:01:27.209 the table every single day. And it's through 00:01:27.209 --> 00:01:29.310 basic operational mistakes, right? We're not 00:01:29.310 --> 00:01:31.670 talking about huge capital investments here. 00:01:31.750 --> 00:01:33.870 Not at all. We're talking about potentially $700 00:01:33.870 --> 00:01:36.209 per cow. Okay. That number, let's be honest, 00:01:36.290 --> 00:01:39.319 it sounds like marketing hype. $700 per cow? 00:01:39.500 --> 00:01:42.040 I mean, that's massive. It is. But what we've 00:01:42.040 --> 00:01:45.159 compiled here is a stack of sources, university 00:01:45.159 --> 00:01:47.840 research, industry field trials, deep dive economic 00:01:47.840 --> 00:01:51.000 modeling that all point to a hard, recoverable 00:01:51.000 --> 00:01:53.840 dollar figure on a frustration every single farmer 00:01:53.840 --> 00:01:55.599 shares. Right. That feeling. I've heard it a 00:01:55.599 --> 00:01:57.640 million times. Exactly. I've heard this from 00:01:57.640 --> 00:02:00.159 countless producers. The ration looks right on 00:02:00.159 --> 00:02:02.280 paper. We have good cows. We invested in the 00:02:02.280 --> 00:02:04.980 genetics. But the bulk tank just isn't consistently 00:02:04.980 --> 00:02:07.329 where it should be. It's that frustration. It 00:02:07.329 --> 00:02:10.370 is. This deep dive is putting a name and a number 00:02:10.370 --> 00:02:13.229 on that persistent efficiency gap. It's not about 00:02:13.229 --> 00:02:15.789 buying a new farm. It's about recovering the 00:02:15.789 --> 00:02:18.469 profit you've already earned. And we need to 00:02:18.469 --> 00:02:21.569 ground that right now. The source material identifies 00:02:21.569 --> 00:02:26.469 $500 to $700 per cow per year in recoverable 00:02:26.469 --> 00:02:29.610 profit. Recoverable. That's the key word. And 00:02:29.610 --> 00:02:33.030 achieved solely through management fixes aimed 00:02:33.030 --> 00:02:35.909 at stabilizing the rumen. So if you're running 00:02:35.909 --> 00:02:39.330 a modest 1 ,000 cow herd, you were talking about 00:02:39.330 --> 00:02:42.610 half a million to $700 ,000 annually. Just sitting 00:02:42.610 --> 00:02:44.250 there waiting to be picked up. I mean, that's 00:02:44.250 --> 00:02:45.810 the difference between a tough year and a very, 00:02:45.830 --> 00:02:48.250 very successful one. It's absolutely life -changing 00:02:48.250 --> 00:02:50.069 money. And this is where we really challenge 00:02:50.069 --> 00:02:52.090 the conventional wisdom, which is, you know, 00:02:52.129 --> 00:02:55.449 the bull vine signature style. For years, when 00:02:55.449 --> 00:02:57.490 farmers chase efficiency, they look at two things. 00:02:57.930 --> 00:03:00.509 Expensive genetics or these huge, complex facility 00:03:00.509 --> 00:03:03.500 upgrades. Right. They think the answer must be 00:03:03.500 --> 00:03:06.659 some new robotic system or a proprietary additive 00:03:06.659 --> 00:03:09.500 that costs a fortune. But the core controversy 00:03:09.500 --> 00:03:11.919 we're getting into today is that the solution, 00:03:12.080 --> 00:03:15.280 the bulk of that $700, it doesn't require a genetic 00:03:15.280 --> 00:03:16.979 breakthrough. It doesn't require a new capital. 00:03:17.199 --> 00:03:20.419 No, it's the operational basics, the boring stuff 00:03:20.419 --> 00:03:23.520 that are failing. Things like weekend feed drift, 00:03:23.879 --> 00:03:26.280 you know, inconsistent crew timing, or those 00:03:26.280 --> 00:03:29.349 unnoticed TMR moisture swings. These are the 00:03:29.349 --> 00:03:32.189 quiet thieves. So we're challenging this ingrained 00:03:32.189 --> 00:03:34.849 notion that if your nutritionist has balanced 00:03:34.849 --> 00:03:37.830 the TMR sheet, the job's done. The job is only 00:03:37.830 --> 00:03:40.530 halfway done. The data we have says the operational 00:03:40.530 --> 00:03:42.830 foundation you lay, that environment you create 00:03:42.830 --> 00:03:45.710 for the rumen microbes, is just as critical as 00:03:45.710 --> 00:03:48.069 the feed ingredients you mix. If you stabilize 00:03:48.069 --> 00:03:51.060 that microbial environment, then your expensive 00:03:51.060 --> 00:03:53.340 genetics and your perfectly formulated ration 00:03:53.340 --> 00:03:56.020 can finally express their full potential. That's 00:03:56.020 --> 00:03:57.979 the whole game. Okay, let's unpack this with 00:03:57.979 --> 00:04:00.180 some hard data, because the industry has really 00:04:00.180 --> 00:04:02.139 been operating on a two -legged stool for too 00:04:02.139 --> 00:04:04.800 long. It has. When we talk about feed efficiency, 00:04:05.120 --> 00:04:08.020 we've historically focused on, well, genetics 00:04:08.020 --> 00:04:11.000 and ration formulation. What the most recent, 00:04:11.080 --> 00:04:13.319 cutting -edge research is telling us is that 00:04:13.319 --> 00:04:16.790 the rumen microbiome is that third critical unseen 00:04:16.790 --> 00:04:19.629 driver this gives serious scientific backing 00:04:19.629 --> 00:04:21.970 to what the best cow people have always known 00:04:21.970 --> 00:04:24.490 in their gut right that feeling when the herd 00:04:24.490 --> 00:04:27.509 is just off even when everything on the paper 00:04:27.509 --> 00:04:29.949 sheet looks perfect the science is finally putting 00:04:29.949 --> 00:04:32.370 quantifiable data behind the impact of those 00:04:32.370 --> 00:04:34.430 gut bugs so what's the headline number what's 00:04:34.430 --> 00:04:36.629 the finding that should make everyone stop and 00:04:36.629 --> 00:04:38.939 listen Okay, the number that needs to stop every 00:04:38.939 --> 00:04:42.279 dairy producer cold comes from 2024 research. 00:04:42.560 --> 00:04:46.040 It was led by H .F. Montero at UC Davis, published 00:04:46.040 --> 00:04:48.500 in the journal Animal Microbiome. This wasn't 00:04:48.500 --> 00:04:50.699 just a simple feeding trial. No, no, this was 00:04:50.699 --> 00:04:53.680 sophisticated stuff. They used an AI -based ensemble 00:04:53.680 --> 00:04:57.060 model, a massive computational model, on a really 00:04:57.060 --> 00:05:00.899 large data set of 454 genotyped Holstein. So 00:05:00.899 --> 00:05:03.069 they were tracking everything. Everything. Diet, 00:05:03.250 --> 00:05:05.509 genetics, and they sampled the microbial populations. 00:05:06.189 --> 00:05:08.910 Their goal was to see what factor best predicted 00:05:08.910 --> 00:05:11.029 which cows were truly efficient. And the key 00:05:11.029 --> 00:05:14.290 finding, the shocking finding, was what? That 00:05:14.290 --> 00:05:16.949 the rumen microbiome accounted for roughly 36 00:05:16.949 --> 00:05:21.030 % of the variation in residual feed intake. RFI. 00:05:21.030 --> 00:05:24.129 36%. I'm still processing that. As a producer, 00:05:24.389 --> 00:05:27.269 you spend massive amounts of time and money on 00:05:27.269 --> 00:05:30.790 genetics, on locking interaction, and you're 00:05:30.790 --> 00:05:32.769 telling me something I can't even see is accounting 00:05:32.769 --> 00:05:34.870 for over a third of the variability in efficiency. 00:05:35.189 --> 00:05:36.930 It completely changes the management priority 00:05:36.930 --> 00:05:40.569 list. It has to. So let's clarify RFI for everyone 00:05:40.569 --> 00:05:42.870 listening. What does that metric actually mean? 00:05:43.029 --> 00:05:44.850 Right. Residual feed intake is basically the 00:05:44.850 --> 00:05:47.670 gold standard for true feed efficiency. It measures 00:05:47.670 --> 00:05:50.050 how much feed the cow actually ate compared to 00:05:50.050 --> 00:05:51.930 how much milk she produced and how big she is, 00:05:51.990 --> 00:05:54.209 all relative to her peers. So a good cow has 00:05:54.209 --> 00:05:57.290 a low RFI. A great cow has a low RFI. She eats 00:05:57.290 --> 00:05:59.920 less than expected for her output. And this UC 00:05:59.920 --> 00:06:02.500 Davis data proves the microbiome isn't just a 00:06:02.500 --> 00:06:05.160 side player. It's a major driver sitting alongside 00:06:05.160 --> 00:06:07.959 genetics and ration, not behind them. So if I'm 00:06:07.959 --> 00:06:11.079 a farmer who's invested heavily in low RFI genetics, 00:06:11.439 --> 00:06:14.620 but my feeding protocol is, let's say, erratic. 00:06:14.860 --> 00:06:18.819 Then you are essentially sabotaging 36 % of the 00:06:18.819 --> 00:06:21.000 genetic potential you just paid top dollar for. 00:06:21.220 --> 00:06:23.399 It's like you said, you bought the Ferrari. Exactly. 00:06:23.519 --> 00:06:25.470 You bought the Ferrari. the genetics and the 00:06:25.470 --> 00:06:28.569 ration, but you're running it on gravel and stalling 00:06:28.569 --> 00:06:30.750 the engine every morning with inconsistent management. 00:06:31.230 --> 00:06:34.310 So the AI model became more accurate when they 00:06:34.310 --> 00:06:37.769 added in the microbiome data. Significantly more 00:06:37.769 --> 00:06:39.949 accurate. The prediction of efficient versus 00:06:39.949 --> 00:06:42.990 inefficient cows improved dramatically when they 00:06:42.990 --> 00:06:45.449 added the microbiome profile data to the genetic 00:06:45.449 --> 00:06:48.949 and diet information. This transition from theoretical 00:06:48.949 --> 00:06:52.689 biology to actionable economics is what makes 00:06:52.689 --> 00:06:55.029 this research so powerful. And what's fascinating 00:06:55.029 --> 00:06:57.089 here is the connection between the cow's genetics 00:06:57.089 --> 00:06:59.850 and her microbial community. There was another 00:06:59.850 --> 00:07:02.750 2024 study, the Host Genome Microbiome Networks 00:07:02.750 --> 00:07:05.089 Project, that dove into this. Wait, I remember 00:07:05.089 --> 00:07:06.990 reading the abstract on that. Didn't they find 00:07:06.990 --> 00:07:09.209 that parts of the core rumen microbiome are actually 00:07:09.209 --> 00:07:13.149 heritable? Yes. It's not just random colonization. 00:07:13.490 --> 00:07:17.490 The ability of a cow to successfully host a highly 00:07:17.490 --> 00:07:21.629 efficient, stable microbial community is influenced 00:07:21.629 --> 00:07:24.860 by her own genetics. So the structure of the 00:07:24.860 --> 00:07:27.819 rumen, her immune response, pH control, that's 00:07:27.819 --> 00:07:30.639 all genetically mediated. Exactly. It creates 00:07:30.639 --> 00:07:32.980 the specific niche for those microbes to thrive 00:07:32.980 --> 00:07:36.000 in. That's a huge paradigm shift. It means the 00:07:36.000 --> 00:07:38.579 cow's genome and her microbial passengers are 00:07:38.579 --> 00:07:41.639 working as this deeply integrated system to shape 00:07:41.639 --> 00:07:44.720 feed utilization and, crucially, methane output. 00:07:44.959 --> 00:07:47.279 It's an efficiency ecosystem. An ecosystem. Perfect 00:07:47.279 --> 00:07:49.759 word for it. And you can't optimize the system 00:07:49.759 --> 00:07:52.079 by only looking at half the players. Okay, let's 00:07:52.079 --> 00:07:53.860 step out of the academic journals for a second 00:07:53.860 --> 00:07:56.519 and talk plain English. What is actually happening 00:07:56.519 --> 00:07:59.579 inside the cow when we disrupt that sensitive 00:07:59.579 --> 00:08:01.959 ecosystem? Because this links directly to what 00:08:01.959 --> 00:08:04.300 you see on the farm floor. It's a constant biological 00:08:04.300 --> 00:08:06.560 tug of war. That's the best way to think about 00:08:06.560 --> 00:08:08.800 it. You have two main teams of microbes competing 00:08:08.800 --> 00:08:11.439 for resources. On one side, you've got the fast 00:08:11.439 --> 00:08:13.759 fermenters. Think of them as the opportunistic 00:08:13.759 --> 00:08:16.720 sprinters. The sugar bugs? The sugar bugs, exactly. 00:08:16.899 --> 00:08:19.100 They thrive on the easy stuff, starch and sugars, 00:08:19.220 --> 00:08:21.339 the rapidly fermentable carbs. They multiply 00:08:21.339 --> 00:08:23.540 like crazy when those resources flood the system. 00:08:23.639 --> 00:08:26.139 And they rapidly produce volatile fatty acids, 00:08:26.319 --> 00:08:29.790 which drops the rumen pH. Fast. And on the other 00:08:29.790 --> 00:08:32.190 side? On the other side, you have the more deliberate, 00:08:32.309 --> 00:08:35.909 slower fiber digesting species, the fibrillitic 00:08:35.909 --> 00:08:38.269 species. These are the marathon runners. We're 00:08:38.269 --> 00:08:40.129 talking about critically important bugs like 00:08:40.129 --> 00:08:42.429 fibrobacter and ruminococcus. These are the ones 00:08:42.429 --> 00:08:44.350 that actually make butterfat. They're the butterfat 00:08:44.350 --> 00:08:47.129 engine. They produce acetate, which directly 00:08:47.129 --> 00:08:50.009 fuels butterfat production. And this is the key. 00:08:50.269 --> 00:08:53.230 These fibrillitic species are incredibly sensitive 00:08:53.230 --> 00:08:56.149 to pH drops. So they don't like an acidic environment. 00:08:56.450 --> 00:08:58.879 They hate it. They like a nice, stable environment, 00:08:59.080 --> 00:09:02.639 typically above a pH of 6. When the fast fermenters 00:09:02.639 --> 00:09:05.159 flood the zone and drop the pH rapidly below 00:09:05.159 --> 00:09:08.259 5 .8, the sensitive fiber digesters get stressed 00:09:08.259 --> 00:09:11.179 out. They slow down their activity, or they can 00:09:11.179 --> 00:09:12.899 even die off and just get washed out of the system 00:09:12.899 --> 00:09:15.019 entirely. So when the feeding environment is 00:09:15.019 --> 00:09:17.440 stable, when the cow is fed consistently, and 00:09:17.440 --> 00:09:19.919 the pH is maintained, they balance out, they 00:09:19.919 --> 00:09:22.580 coexist. And you get maximal fiber digestion, 00:09:23.019 --> 00:09:25.720 steady component production, everything's humming 00:09:25.720 --> 00:09:29.070 along. But the moment we change the rules, the 00:09:29.070 --> 00:09:31.710 moment we introduce inconsistent feeding, slug 00:09:31.710 --> 00:09:34.490 feeding, or those TMR moisture swings. The fast 00:09:34.490 --> 00:09:37.370 opportunists win. They drop the pH, they inhibit 00:09:37.370 --> 00:09:39.850 the fiber digesters, and now you have a less 00:09:39.850 --> 00:09:42.629 efficient rumen. The cow is passing valuable 00:09:42.629 --> 00:09:45.389 fiber, you know, your expensive haylage and corn 00:09:45.389 --> 00:09:48.230 silage, right through her system undigested. 00:09:48.350 --> 00:09:50.529 She's losing potential butterfat. And she's losing 00:09:50.529 --> 00:09:53.710 36 % of her efficiency potential. It's that simple. 00:09:54.080 --> 00:09:56.080 So what does that look like when you walk the 00:09:56.080 --> 00:09:59.100 barn? What are the on -farm symptoms of that 00:09:59.100 --> 00:10:01.580 microbial instability that a farmer can actually 00:10:01.580 --> 00:10:03.679 see with their own eyes? The first thing you 00:10:03.679 --> 00:10:05.700 usually notice is bouncing butterfat levels. 00:10:05.899 --> 00:10:08.179 You look at the DHIA report and the component 00:10:08.179 --> 00:10:10.779 percentages are just erratic day -to -day or 00:10:10.779 --> 00:10:12.820 week -to -week, and you know you haven't changed 00:10:12.820 --> 00:10:15.840 the ration or the forage. It's the bugs. It's 00:10:15.840 --> 00:10:18.919 the bugs. It's that microbial community cycling 00:10:18.919 --> 00:10:21.559 through shock and recovery. And what about fresh 00:10:21.559 --> 00:10:24.190 cows? It's those fresh cows who are stalling 00:10:24.190 --> 00:10:27.309 out. The ration sheet says they should be aggressively 00:10:27.309 --> 00:10:30.070 ramping up their dry matter intake, their DMI, 00:10:30.269 --> 00:10:33.200 but they just aren't. They hit a wall at 50 pounds 00:10:33.200 --> 00:10:35.320 of milk and you can't push them higher even though 00:10:35.320 --> 00:10:37.519 the feed is perfectly formulated for them. So 00:10:37.519 --> 00:10:39.120 you're just burning money on feed they can't 00:10:39.120 --> 00:10:41.480 convert? Absolutely. And I think the most common 00:10:41.480 --> 00:10:44.419 insidious observation is just the general off 00:10:44.419 --> 00:10:47.179 days. You walk the barn, the rumination index 00:10:47.179 --> 00:10:49.639 on your collars is dipping, manure consistency 00:10:49.639 --> 00:10:52.240 is erratic, maybe a little more loose or bubbly. 00:10:52.379 --> 00:10:54.620 The cows just look a little sluggish. Exactly. 00:10:54.740 --> 00:10:59.190 It's not frank acidosis. But it's subacute ruminacidosis, 00:10:59.190 --> 00:11:01.929 Sarah. That means they are in a constant state 00:11:01.929 --> 00:11:05.070 of mild distress because of the operational shocks 00:11:05.070 --> 00:11:07.909 we keep introducing. And that shock, as the sources 00:11:07.909 --> 00:11:09.909 reveal, almost always comes from one of three 00:11:09.909 --> 00:11:11.789 places that are entirely within the farmer's 00:11:11.789 --> 00:11:15.590 control. Inconsistent timing, TMR moisture swings, 00:11:15.750 --> 00:11:18.409 or the cow's ability to sort the feed. That's 00:11:18.409 --> 00:11:20.690 the trifecta of failure. The science is just 00:11:20.690 --> 00:11:23.470 overwhelming on this. You either manage the environment 00:11:23.470 --> 00:11:27.809 for the bugs, Or you watch 36 % of your feed 00:11:27.809 --> 00:11:30.950 efficiency potential drain away into the manure 00:11:30.950 --> 00:11:33.190 lagoon. Okay, let's jump straight to the first 00:11:33.190 --> 00:11:35.490 and maybe the most actionable management lever. 00:11:35.590 --> 00:11:38.549 That's feed timing and access. This is where 00:11:38.549 --> 00:11:41.090 we start building the case for that $700 per 00:11:41.090 --> 00:11:44.470 cow because this operational consistency, or 00:11:44.470 --> 00:11:47.610 lack thereof, is the biggest disruptor on farms 00:11:47.610 --> 00:11:50.230 of all sizes. You call this the Saturday morning 00:11:50.230 --> 00:11:52.330 problem. I do, because I'm just not buying the 00:11:52.330 --> 00:11:55.029 story that every farm has perfect military -grade 00:11:55.029 --> 00:11:57.629 6 a .m. feeding seven days a week. It just doesn't 00:11:57.629 --> 00:11:59.490 happen. Right. During the week, maybe the main 00:11:59.490 --> 00:12:02.029 crew is tight. You know, 6 a .m. feeding, midday 00:12:02.029 --> 00:12:03.990 push -up, 10 p .m. push -up. Then the weekend 00:12:03.990 --> 00:12:06.950 hits. Or a holiday. Or the regular feeder is 00:12:06.950 --> 00:12:09.529 out sick. And suddenly, that 6 a .m. delivery 00:12:09.529 --> 00:12:12.950 drifts to 7, maybe 7 .30. Right. Or perhaps the 00:12:12.950 --> 00:12:15.549 last push -up happens at 8 p .m. instead of 11. 00:12:15.769 --> 00:12:18.029 That little drift might seem insignificant to 00:12:18.029 --> 00:12:19.879 the crew. But to the cow, and especially to our 00:12:19.879 --> 00:12:22.240 microbes, it's a complete shift in her whole 00:12:22.240 --> 00:12:25.700 routine. A shock to the system. And on larger 00:12:25.700 --> 00:12:27.519 dairies, it's not always just about the weekend. 00:12:27.779 --> 00:12:30.340 It can be inconsistent crew handoffs. That's 00:12:30.340 --> 00:12:32.559 a huge one. If you have multiple shifts or multiple 00:12:32.559 --> 00:12:35.259 feeder drivers, one person might be religious 00:12:35.259 --> 00:12:37.340 about making sure the bunk is clean at the next 00:12:37.340 --> 00:12:40.759 feeding, and the next feeder is... looser with 00:12:40.759 --> 00:12:43.240 timing. To the microbial community, that is just 00:12:43.240 --> 00:12:46.279 an irregular routine. And microbes, unlike humans, 00:12:46.580 --> 00:12:49.360 thrive on painful predictability. They want the 00:12:49.360 --> 00:12:52.399 exact same thing at the exact same time every 00:12:52.399 --> 00:12:54.779 single day. We can speculate about the impact 00:12:54.779 --> 00:12:58.100 of that timing drift, but Penn State researchers... 00:12:58.460 --> 00:13:01.240 brought the absolute hammer down with some quantifiable 00:13:01.240 --> 00:13:03.399 data on this. This is the stuff that needs to 00:13:03.399 --> 00:13:04.980 be pinned up in the feed room. What did they 00:13:04.980 --> 00:13:07.159 find? In their summary of work on feed access, 00:13:07.460 --> 00:13:09.679 they looked at cows that experienced a typical 00:13:09.679 --> 00:13:12.220 long overnight feed gap. And they found that 00:13:12.220 --> 00:13:14.539 cows restricted from feed for about 10 hours, 00:13:14.700 --> 00:13:16.840 which, let's be honest, is a very typical overnight 00:13:16.840 --> 00:13:18.860 reality on a lot of farms that don't push feed 00:13:18.860 --> 00:13:23.200 late. They ate 3 .5 pounds less dry matter, DMI. 00:13:23.480 --> 00:13:27.009 Wait, hold up. Three and a half pounds DMI loss 00:13:27.009 --> 00:13:31.090 per day. That is an automatic, non -recoverable 00:13:31.090 --> 00:13:33.470 loss of potential energy intake every single 00:13:33.470 --> 00:13:37.009 day. That alone should have every producer scrambling 00:13:37.009 --> 00:13:39.809 to change their schedule. It gets worse. The 00:13:39.809 --> 00:13:42.970 output is the most painful metric. Those same 00:13:42.970 --> 00:13:47.730 cows produced 7 .9 pounds less milk per day than 00:13:47.730 --> 00:13:51.490 the cows with continuous access. 7 .9, nearly 00:13:51.490 --> 00:13:54.889 8 pounds. We are not talking about marginal losses 00:13:54.889 --> 00:13:56.669 here. We're talking about nearly eight pounds 00:13:56.669 --> 00:14:00.250 of milk per cow per day purely because the bunk 00:14:00.250 --> 00:14:02.730 was empty too long overnight. That is the single 00:14:02.730 --> 00:14:05.210 most important actionable data point we have 00:14:05.210 --> 00:14:07.409 seen in months because it's not an expensive 00:14:07.409 --> 00:14:09.929 fix. An eight pound swing just for tightening 00:14:09.929 --> 00:14:12.389 up overnight feed access. And you see this mirrored 00:14:12.389 --> 00:14:14.779 across the literature. Herds that were routinely 00:14:14.779 --> 00:14:17.720 pushing feed up late produced, on average, over 00:14:17.720 --> 00:14:19.799 eight pounds more milk than herds that either 00:14:19.799 --> 00:14:22.379 didn't push feed or pushed it inconsistently. 00:14:22.480 --> 00:14:24.419 Let's talk about the microbial mechanism there 00:14:24.419 --> 00:14:27.179 because it explains that extreme loss. It's brutally 00:14:27.179 --> 00:14:29.519 simple physiology. What's happening in the rumen? 00:14:29.559 --> 00:14:31.919 When the bunk is empty for too long, say over 00:14:31.919 --> 00:14:35.200 three or four hours, the cows get seriously hungry. 00:14:35.659 --> 00:14:38.340 Their motivation to eat is massive and their 00:14:38.340 --> 00:14:41.019 internal rumen motility just increases dramatically. 00:14:41.759 --> 00:14:44.759 So when the TMR finally arrives, whether it's 00:14:44.759 --> 00:14:47.860 the 6 a .m. load or that midnight push -up, they're 00:14:47.860 --> 00:14:49.759 going to do what's called slug feeding. They 00:14:49.759 --> 00:14:52.860 consume a massive meal volume very, very quickly 00:14:52.860 --> 00:14:55.360 because they're making up for lost time. And 00:14:55.360 --> 00:14:57.960 slug feeding is a guaranteed recipe for a sharp 00:14:57.960 --> 00:15:01.000 pathological pH drop. Guaranteed. You've just... 00:15:01.200 --> 00:15:03.360 dumped a huge load of highly fermentable carbohydrates, 00:15:03.659 --> 00:15:06.259 all your starches, sugars, proteins, into the 00:15:06.259 --> 00:15:08.700 rumen all at once. The fast fermenters have a 00:15:08.700 --> 00:15:11.279 massive buffet. And they multiply and produce 00:15:11.279 --> 00:15:13.799 acid faster than the cow's natural buffer system 00:15:13.799 --> 00:15:16.539 or saliva can cope with. That rapid acid production 00:15:16.539 --> 00:15:19.220 immediately stresses those sensitive, slower, 00:15:19.360 --> 00:15:21.860 fibrolytic species we talked about, the ruminococcus 00:15:21.860 --> 00:15:25.080 and fibrobacter populations. The pH crashes below 00:15:25.080 --> 00:15:27.720 5 .8, they slow down, fiber digestion halts, 00:15:27.740 --> 00:15:29.360 and you start seeing all the symptoms of sera. 00:15:29.519 --> 00:15:32.100 So inconsistent feeding is literally administering 00:15:32.100 --> 00:15:34.639 a daily acid shock to the cow's digestive engine. 00:15:34.779 --> 00:15:36.960 Every single time. And if you do that every night 00:15:36.960 --> 00:15:39.700 or every weekend, the microbial community never 00:15:39.700 --> 00:15:42.840 gets a chance to stabilize. It's a constant cycle 00:15:42.840 --> 00:15:46.080 of shock, recovery, and inefficiency. The losses 00:15:46.080 --> 00:15:48.440 just stack up. So science says the actionable 00:15:48.440 --> 00:15:51.139 rule of thumb here is non -negotiable then. Bunks 00:15:51.139 --> 00:15:53.460 should not be empty for more than about three 00:15:53.460 --> 00:15:55.980 hours in your high producing groups. Period. 00:15:56.179 --> 00:15:59.049 Three hours. That sets a clear metric for management. 00:15:59.250 --> 00:16:01.330 And that means push -ups are not just, you know, 00:16:01.330 --> 00:16:03.710 an aesthetic duty to make the bunk look nice. 00:16:03.990 --> 00:16:06.570 They are a physiological necessity that prevents 00:16:06.570 --> 00:16:09.529 slug feeding. You need more frequent push -ups 00:16:09.529 --> 00:16:11.269 in the first three to four hours after feeding, 00:16:11.350 --> 00:16:14.149 and critically, a final push -up before the night 00:16:14.149 --> 00:16:16.509 crew leaves to ensure feed is available until 00:16:16.509 --> 00:16:18.710 that morning load arrives. This is just critical 00:16:18.710 --> 00:16:21.539 for stabilizing DMI and maximizing yield. And 00:16:21.539 --> 00:16:23.960 we can't forget the transition cow angle either. 00:16:24.179 --> 00:16:26.779 The studies on transition cow management show 00:16:26.779 --> 00:16:29.320 that more consistent routines and that feeding 00:16:29.320 --> 00:16:31.840 schedule is the ultimate time cue for a cow lead 00:16:31.840 --> 00:16:35.100 to better metabolic profiles and stronger, less 00:16:35.100 --> 00:16:38.500 problematic early lactation performance. So disrupting 00:16:38.500 --> 00:16:40.379 that feeding cue right when she's metabolically 00:16:40.379 --> 00:16:42.919 fragile is just asking for trouble. You're asking 00:16:42.919 --> 00:16:46.360 for DAs and early lactation stalls. So. If the 00:16:46.360 --> 00:16:49.240 first phase of recovering the $700 per cow is 00:16:49.240 --> 00:16:51.600 purely about establishing and maintaining rigid 00:16:51.600 --> 00:16:54.200 consistency and timing, the investment cost is 00:16:54.200 --> 00:16:56.960 low. Mostly labor and discipline. But the return 00:16:56.960 --> 00:16:59.879 is massive. Potentially recovering eight pounds 00:16:59.879 --> 00:17:02.879 of milk per cow per day. It's the highest leverage 00:17:02.879 --> 00:17:04.900 point, absolutely. And that's why it has to be 00:17:04.900 --> 00:17:08.220 phase one of any recovery plan. Okay, so if erratic 00:17:08.220 --> 00:17:11.740 timing is the noisy operational thief, then TMR 00:17:11.740 --> 00:17:14.680 dry matter inconsistency is the quiet one. This 00:17:14.680 --> 00:17:17.359 is our second management lever, and it is a major 00:17:17.359 --> 00:17:20.400 profit leak that farmers often miss because they're 00:17:20.400 --> 00:17:22.900 managing the weight of the feed. Not the actual 00:17:22.900 --> 00:17:24.980 nutrient content. And this is exactly what happens. 00:17:25.140 --> 00:17:28.200 The TMR sheet is based on an expected dry matter, 00:17:28.380 --> 00:17:31.220 say 50 % for haylage. But if that haylage moisture 00:17:31.220 --> 00:17:34.359 shifts to 55 % because of rain or moving to a 00:17:34.359 --> 00:17:36.380 wetter section of the bunker... And the batch 00:17:36.380 --> 00:17:38.380 weights on the mixer wagon stay the same. The 00:17:38.380 --> 00:17:41.099 cow consumes the same volume of TMR. The bunk 00:17:41.099 --> 00:17:43.880 looks just as full, but she is ingesting significantly 00:17:43.880 --> 00:17:47.099 less actual dry matter and therefore less energy 00:17:47.099 --> 00:17:49.619 and nutrient content. She fills up faster on 00:17:49.619 --> 00:17:52.700 water. She's full, but she's underfed. And when 00:17:52.700 --> 00:17:56.059 DMI drops by 5 % overnight because of that simple 00:17:56.059 --> 00:17:59.319 moisture swing, milk production drops a few pounds 00:17:59.319 --> 00:18:02.000 per cow per day. And for a week, Sarah, nobody 00:18:02.000 --> 00:18:04.880 knows why. Everyone blames the weather. or the 00:18:04.880 --> 00:18:07.259 milk processor. Until someone finally grabs the 00:18:07.259 --> 00:18:09.819 coaster tester and realizes that TMR is soupier 00:18:09.819 --> 00:18:11.819 than expected. The Penn State team highlights 00:18:11.819 --> 00:18:13.700 this by showing that herds that consistently 00:18:13.700 --> 00:18:17.019 keep their actual DMI within 5 % of expected 00:18:17.019 --> 00:18:20.099 intakes, which absolutely requires strict routine 00:18:20.099 --> 00:18:23.180 TMR dry matter measurement and adjustment, are 00:18:23.180 --> 00:18:25.099 the ones who consistently achieve higher milk 00:18:25.099 --> 00:18:27.460 yield and stable components. The lack of routine 00:18:27.460 --> 00:18:30.000 DM checks is an invisible tax on your profit 00:18:30.000 --> 00:18:32.160 stability. And again, the microbiome feels it 00:18:32.160 --> 00:18:33.880 immediately, but in two opposite directions. 00:18:33.900 --> 00:18:37.000 Right. If the TMR is suddenly wetter, the passage 00:18:37.000 --> 00:18:39.500 rate speeds up. The feed just moves through the 00:18:39.500 --> 00:18:42.359 rumen quicker. That gives those fibrillitic bacteria 00:18:42.359 --> 00:18:44.700 less time to colonize, break down the fiber, 00:18:44.799 --> 00:18:47.200 and maximize VFA production. Efficiency just 00:18:47.200 --> 00:18:49.740 tanks. And on the flip side, if the TMR gets 00:18:49.740 --> 00:18:52.559 drier, maybe the corn silage is suddenly drier 00:18:52.559 --> 00:18:55.480 than expected? And you don't adjust. You are 00:18:55.480 --> 00:18:57.980 packing more concentrated dry matter and fermentable 00:18:57.980 --> 00:19:01.220 energy into that same meal volume. The fermentation 00:19:01.220 --> 00:19:04.460 runs incredibly hot. The rumen pH drops much 00:19:04.460 --> 00:19:07.019 sharper. And you stress the microbial community 00:19:07.019 --> 00:19:10.279 straight towards acidosis. So it's a lose -lose 00:19:10.279 --> 00:19:12.279 scenario if you don't adjust. It's a total lose 00:19:12.279 --> 00:19:15.119 -lose. So the fix, again, is simple in concept, 00:19:15.180 --> 00:19:17.920 but it requires discipline in execution. How 00:19:17.920 --> 00:19:20.160 often should we be testing the TMR dry matter? 00:19:20.619 --> 00:19:22.420 The consensus from the consultant nutritionist 00:19:22.420 --> 00:19:24.660 we reviewed is you need to be testing TMR dry 00:19:24.660 --> 00:19:27.140 matter at least once or twice a week, routinely. 00:19:27.640 --> 00:19:29.460 But more importantly, you have to test every 00:19:29.460 --> 00:19:31.859 time you switch bunker sections, move forage 00:19:31.859 --> 00:19:34.039 sources, or after a heavy rainfall that could 00:19:34.039 --> 00:19:36.559 soak the feed face. And you must log the numbers. 00:19:36.680 --> 00:19:39.559 You need a formal, non -negotiable trigger. When 00:19:39.559 --> 00:19:42.099 the TMR dry matter moves outside a reasonable 00:19:42.099 --> 00:19:44.259 band, say, a two -point or greater difference 00:19:44.259 --> 00:19:46.440 from the target, the batch weights have to be 00:19:46.440 --> 00:19:48.660 adjusted immediately. You cannot wait for the 00:19:48.660 --> 00:19:50.920 nutritionist to visit next week. That protocol, 00:19:51.200 --> 00:19:53.799 formalized and disciplined, prevents the majority 00:19:53.799 --> 00:19:56.460 of those mystery milk drops that frustrate everyone. 00:19:56.740 --> 00:19:59.960 It turns a reactive farm, you know, chasing drops, 00:20:00.140 --> 00:20:02.299 into a proactive farm that maintains stability. 00:20:02.720 --> 00:20:05.200 Okay, let's move to the third lever in this management 00:20:05.200 --> 00:20:08.700 trifecta. Particle size and sorting. This is 00:20:08.700 --> 00:20:10.700 the visual confirmation of microbiome disruption. 00:20:11.230 --> 00:20:14.089 what you call the three rations in one bunk problem. 00:20:14.349 --> 00:20:16.710 Every dairy farmer knows this image. You deliver 00:20:16.710 --> 00:20:19.710 a supposedly perfect TMR balance mixed correctly. 00:20:20.049 --> 00:20:22.630 You walk the bunk 60 minutes later, and there 00:20:22.630 --> 00:20:25.269 are these distinct piles of long structural fiber 00:20:25.269 --> 00:20:28.230 straw, long haylage stems pushed away into a 00:20:28.230 --> 00:20:31.049 neat pile. The cow has literally engineered her 00:20:31.049 --> 00:20:34.049 own diet. She surgically removes the fine, rich, 00:20:34.069 --> 00:20:36.430 starchy stuff, leaving the structural fiber she 00:20:36.430 --> 00:20:39.079 needs for rumination. The paper ration says she's 00:20:39.079 --> 00:20:42.279 getting X fiber and Y starch, but the eaten ration 00:20:42.279 --> 00:20:44.859 is something completely different. It's a diet 00:20:44.859 --> 00:20:47.059 much richer in starch and poorer in effective 00:20:47.059 --> 00:20:50.299 fiber than was ever intended. That is a recipe 00:20:50.299 --> 00:20:53.039 for acidosis, regardless of what the nutritionist 00:20:53.039 --> 00:20:56.160 formulated. The cow is voluntarily slug -feeding 00:20:56.160 --> 00:20:59.099 on a starch -heavy diet, which guarantees a pH 00:20:59.099 --> 00:21:01.640 crash. And this is why the Penn State Particle 00:21:01.640 --> 00:21:04.420 Separator, the PSPS, isn't just a suggestion. 00:21:04.599 --> 00:21:07.980 It's an absolute requirement for auditing the 00:21:07.980 --> 00:21:11.019 eaten ration. We need to be running it weekly 00:21:11.019 --> 00:21:13.480 to catch this behavioral and physical sorting 00:21:13.480 --> 00:21:16.980 issue before it costs us components. Let's talk 00:21:16.980 --> 00:21:19.359 specific targets, because the audience needs 00:21:19.359 --> 00:21:21.240 to know what they should be seeing in those shaker 00:21:21.240 --> 00:21:23.880 boxes. For high -producing, corn silage -based 00:21:23.880 --> 00:21:26.720 rations, the Penn State guidance is very specific, 00:21:26.859 --> 00:21:28.819 and every producer should know these numbers 00:21:28.819 --> 00:21:31.400 by heart. Okay, lay them out. First, the top 00:21:31.400 --> 00:21:33.819 sieve, the really long stuff, should only hold 00:21:33.819 --> 00:21:37.000 2 -8 % of the material. You're seeing 15 % there, 00:21:37.099 --> 00:21:39.220 you've guaranteed sorting. The cow won't eat 00:21:39.220 --> 00:21:41.880 that fraction anyway. Next, the second sieve 00:21:41.880 --> 00:21:44.539 is the core structural stuff, the physically 00:21:44.539 --> 00:21:48.000 effective fiber. You want 30 -50 % there. That 00:21:48.000 --> 00:21:50.660 provides the scratch factor. Then the next sieve 00:21:50.660 --> 00:21:54.920 down, the 4mm sieve, should have 10 -20%. This 00:21:54.920 --> 00:21:57.660 is the material that promotes rumination. And 00:21:57.660 --> 00:22:00.890 finally, The bottom pan, the fines, should have 00:22:00.890 --> 00:22:03.890 no more than 30 to 40 percent for high producing 00:22:03.890 --> 00:22:06.730 cows. And if you see 50 or 60 percent in the 00:22:06.730 --> 00:22:08.950 bottom pan, the ration is too powdery and you're 00:22:08.950 --> 00:22:11.269 just promoting rapid fermentation and acidosis. 00:22:11.309 --> 00:22:14.789 That 2 to 8 percent on the top sieve is so critical. 00:22:14.869 --> 00:22:16.970 If the particles are too long, they just reduce 00:22:16.970 --> 00:22:19.930 DMI because the cow has to spend too much time 00:22:19.930 --> 00:22:22.400 sorting or she just gives up altogether. Hoard's 00:22:22.400 --> 00:22:24.220 article will cite research showing that overly 00:22:24.220 --> 00:22:27.180 long particles reduce DMI by a significant five 00:22:27.180 --> 00:22:29.240 to six pounds per day. And that was recovered 00:22:29.240 --> 00:22:31.359 immediately when the ration structure was adjusted 00:22:31.359 --> 00:22:34.140 to meet those PSPS targets. Five to six pounds 00:22:34.140 --> 00:22:37.299 of DMI lost is catastrophic. That is pure profit 00:22:37.299 --> 00:22:40.000 walking away from the bunk. And from the microbial 00:22:40.000 --> 00:22:42.259 perspective, that constant sorting acts like 00:22:42.259 --> 00:22:45.019 a daily self -inflicted shock. By picking out 00:22:45.019 --> 00:22:47.779 the starch, the cow is constantly pushing her 00:22:47.779 --> 00:22:49.559 rumen toward the fast -fermenting organisms. 00:22:50.329 --> 00:22:53.069 She's starving the fiber digesters of the consistent 00:22:53.069 --> 00:22:55.650 environment they need to do their job. It's the 00:22:55.650 --> 00:22:58.210 cow making a rational but biologically destructive 00:22:58.210 --> 00:23:01.029 choice. She's looking for the energy -dense bits, 00:23:01.230 --> 00:23:03.849 and we as managers failed to present her with 00:23:03.849 --> 00:23:06.230 a diet that forces her to eat the fiber and the 00:23:06.230 --> 00:23:08.690 energy together. So whether you are running a 00:23:08.690 --> 00:23:10.890 large free -saw or a small tie -stall operation, 00:23:11.390 --> 00:23:14.450 auditing that eat -and -ration with a PSPS and 00:23:14.450 --> 00:23:17.130 physically watching the bunk 45 to 60 minutes 00:23:17.130 --> 00:23:20.160 after feeding is essential. The goal is to eliminate 00:23:20.160 --> 00:23:22.819 the gap between the paper ration and the biological 00:23:22.819 --> 00:23:25.299 reality of what the cow is actually ingesting. 00:23:25.460 --> 00:23:28.059 We've identified the three core operational thieves. 00:23:28.700 --> 00:23:32.599 Erratic timing, fluctuating TMR dry matter, and 00:23:32.599 --> 00:23:34.640 sorting. Now we need the roadmap. We can't just 00:23:34.640 --> 00:23:37.099 tell people to do all three things at once. The 00:23:37.099 --> 00:23:39.380 sources outline a very logical, sequential strategy. 00:23:39.700 --> 00:23:42.319 The four -phase playbook. Right. This is designed 00:23:42.319 --> 00:23:45.019 to be a sustained management project, not a weekend 00:23:45.019 --> 00:23:48.299 fix. And the sequence is vital. You cannot try 00:23:48.299 --> 00:23:50.500 to fine -tune the system with expensive additives 00:23:50.500 --> 00:23:53.480 in Phase 4 if the foundation is cracked because 00:23:53.480 --> 00:23:56.059 you're failing Phase 1 and 2. Okay, let's start 00:23:56.059 --> 00:23:59.140 with Phase 1. Tighten timing. and feed access. 00:23:59.480 --> 00:24:02.980 This is the honesty phase. You cannot rely on 00:24:02.980 --> 00:24:06.180 memory or assumptions. You have to log the actual 00:24:06.180 --> 00:24:08.759 feed delivery and push -up times for two weeks, 00:24:08.859 --> 00:24:11.200 including weekends and holidays. You have to 00:24:11.200 --> 00:24:13.500 identify those recurring feed gaps longer than 00:24:13.500 --> 00:24:16.140 the three hour maximum. The goal here is immediate 00:24:16.140 --> 00:24:19.099 reduction of the daily microbial shock. We saw 00:24:19.099 --> 00:24:21.960 the data. Moving cows from restricted access 00:24:21.960 --> 00:24:24.400 to continuous access can recover nearly eight 00:24:24.400 --> 00:24:27.269 pounds of milk. That first $100 ,000 to $120 00:24:27.269 --> 00:24:30.329 ,000 in recovered profit for a thousand cow herd 00:24:30.329 --> 00:24:32.630 is sitting right here. A farmer might push back 00:24:32.630 --> 00:24:34.849 and say, I don't have the labor budget for a 00:24:34.849 --> 00:24:37.190 midnight push -up. How do they implement this 00:24:37.190 --> 00:24:39.430 sustainably? That's a fair point. You have to 00:24:39.430 --> 00:24:41.690 decide what's realistic. If a human contractor 00:24:41.690 --> 00:24:44.390 isn't possible, then phase one becomes an investment 00:24:44.390 --> 00:24:47.000 decision, an automatic feed pusher. If you can 00:24:47.000 --> 00:24:50.980 justify $100 ,000 in recovered milk, a $20 ,000 00:24:50.980 --> 00:24:53.660 investment in a pusher that operates three extra 00:24:53.660 --> 00:24:56.180 times a night becomes a no -brainer. But even 00:24:56.180 --> 00:24:58.740 without that, you have to prioritize eliminating 00:24:58.740 --> 00:25:01.880 the single longest gap, usually that overnight 00:25:01.880 --> 00:25:04.880 stretch. Yeah. Just adjusting crew handoffs to 00:25:04.880 --> 00:25:07.640 ensure the last pushes later can make a massive 00:25:07.640 --> 00:25:09.980 difference. Once phase one is locked in, the 00:25:09.980 --> 00:25:12.559 feed is consistently available, then you can 00:25:12.559 --> 00:25:15.380 move to phase two. Tune up the physical ration? 00:25:15.700 --> 00:25:17.819 Right. You can't worry about particle size if 00:25:17.819 --> 00:25:20.859 the bunk is empty for six hours every day. Now 00:25:20.859 --> 00:25:23.180 that the feed is always there, you focus on what 00:25:23.180 --> 00:25:25.579 it looks like. This is where the PSPS moves from 00:25:25.579 --> 00:25:27.640 a troubleshooting tool to a routine management 00:25:27.640 --> 00:25:30.579 check. Run it weekly for a month to establish 00:25:30.579 --> 00:25:33.440 a stable baseline. Then work with your nutritionist 00:25:33.440 --> 00:25:35.640 to adjust chop length, kernel processing, and 00:25:35.640 --> 00:25:38.200 especially mixing time. The physical goal is 00:25:38.200 --> 00:25:40.619 to make the ration chewable, which stimulates 00:25:40.619 --> 00:25:43.269 saliva, and acts as the cow's natural buffer, 00:25:43.390 --> 00:25:46.190 but not easily sortable. The ultimate test for 00:25:46.190 --> 00:25:49.670 phase two is observational. Spend 45 to 60 minutes 00:25:49.670 --> 00:25:51.630 standing at the bunk after feeding your high 00:25:51.630 --> 00:25:54.190 producers. If the cows have already sorted it, 00:25:54.309 --> 00:25:56.869 you failed phase two. You need to adjust your 00:25:56.869 --> 00:25:59.470 mixer wagon schedule or chop length immediately. 00:25:59.869 --> 00:26:01.789 It's about making sure the ration the cow wants 00:26:01.789 --> 00:26:04.150 to eat is the one she needs to eat. Next up, 00:26:04.230 --> 00:26:07.259 phase three. Make dry matter checking routine. 00:26:07.579 --> 00:26:10.440 You fixed timing and structure. Now you demand 00:26:10.440 --> 00:26:13.740 consistency. Set fixed non -negotiable times 00:26:13.740 --> 00:26:16.059 each week, say Monday morning and Thursday afternoon, 00:26:16.279 --> 00:26:18.640 or more frequently if weather demands it, to 00:26:18.640 --> 00:26:21.359 test the TMR dry matter. And you have to log 00:26:21.359 --> 00:26:23.960 those numbers in a permanent location. And crucially, 00:26:24.019 --> 00:26:27.000 agree on a trigger. We recommend a simple two 00:26:27.000 --> 00:26:28.819 -point or greater difference from the target 00:26:28.819 --> 00:26:31.220 DM percentage means an automatic batch weight 00:26:31.220 --> 00:26:34.220 adjustment. This takes the emotion and the procrastination 00:26:34.220 --> 00:26:36.759 out of it. You are formalizing management to 00:26:36.759 --> 00:26:39.119 prevent those half a kilo per day losses that 00:26:39.119 --> 00:26:41.980 creep in silently during bad weeks. Only when 00:26:41.980 --> 00:26:44.599 those three foundational phases are utterly solid, 00:26:44.740 --> 00:26:47.839 meaning you have consistent timing, a non -sortable 00:26:47.839 --> 00:26:51.859 physical ration, and stable TMR dry matter, do 00:26:51.859 --> 00:26:55.220 you even consider phase four. Use additives to 00:26:55.220 --> 00:26:59.130 fine -tune, not patch. This is the bovine skeptical 00:26:59.130 --> 00:27:03.170 check. We are not buying the idea that a $5 per 00:27:03.170 --> 00:27:06.670 cow live yeast product fixes a $500 management 00:27:06.670 --> 00:27:08.769 problem. And the research supports this too. 00:27:08.910 --> 00:27:11.390 The clinical trials, like those by Marino and 00:27:11.390 --> 00:27:13.309 colleagues on live yeast, show that they can 00:27:13.309 --> 00:27:15.789 deliver improved DMI, better rumination, and 00:27:15.789 --> 00:27:19.079 1 to 2 kilograms per day of milk gains. That's 00:27:19.079 --> 00:27:21.559 real money. But there's a big caveat. A huge 00:27:21.559 --> 00:27:23.839 one. That research is almost always conducted 00:27:23.839 --> 00:27:25.940 in well -managed herds where the basics are already 00:27:25.940 --> 00:27:27.900 locked in. The extension reviews are crystal 00:27:27.900 --> 00:27:30.559 clear. Yeast and buffers cannot overcome structural 00:27:30.559 --> 00:27:33.220 issues like long feed restriction gaps, poor 00:27:33.220 --> 00:27:35.920 forage, excessive stocking density, or ventilation 00:27:35.920 --> 00:27:38.559 problems. If you introduce a yeast product into 00:27:38.559 --> 00:27:40.799 a system that still has an eight -hour overnight 00:27:40.799 --> 00:27:43.579 feed gap and assortable ration, you are just 00:27:43.579 --> 00:27:46.839 providing a marginal effect on an unstable system. 00:27:47.000 --> 00:27:49.440 You have to address fundamentals first to unlock 00:27:49.440 --> 00:27:51.500 the full potential of those additives. They're 00:27:51.500 --> 00:27:54.420 the icing, not the cake. Exactly. So let's talk 00:27:54.420 --> 00:27:57.180 scalability. How does this four -phase plan apply 00:27:57.180 --> 00:28:00.079 to different operation types? Because the levers 00:28:00.079 --> 00:28:02.519 are different. For small family herds or pea 00:28:02.519 --> 00:28:05.200 stall operations, the advantage is quick reaction 00:28:05.200 --> 00:28:08.519 time. The constraint is always labor. They should 00:28:08.519 --> 00:28:10.980 focus heavily on keeping feed times ridiculously 00:28:10.980 --> 00:28:13.799 consistent, even if it means changing the family 00:28:13.799 --> 00:28:16.099 schedule. And add a simple, consistent weekly 00:28:16.099 --> 00:28:19.200 DM check using a coaster tester. They might restrict 00:28:19.200 --> 00:28:21.839 expensive Phase 4 additives only to the highest 00:28:21.839 --> 00:28:24.900 risk animals, like fresh cows, for maximum ROI. 00:28:25.279 --> 00:28:28.940 What about grazing or seasonal systems? The focus 00:28:28.940 --> 00:28:31.240 shifts away from the mixer wagon there. They 00:28:31.240 --> 00:28:33.480 still need consistency, but it's delivered through 00:28:33.480 --> 00:28:36.299 different cues. The questions change. Is turnout 00:28:36.299 --> 00:28:39.380 time consistent? Is the parlor concentrate timing 00:28:39.380 --> 00:28:42.339 predictable and smooth? And critically, are the 00:28:42.339 --> 00:28:44.460 transitions moving from conserved feed in the 00:28:44.460 --> 00:28:48.339 spring to lush pasture smooth to avoid that massive 00:28:48.339 --> 00:28:51.089 microbial shock? They manage the fence line and 00:28:51.089 --> 00:28:53.569 the parlor, not just the bunk. And for large, 00:28:53.589 --> 00:28:56.430 hot, dry lot systems in the Southwest, heat stress 00:28:56.430 --> 00:29:00.029 adds a massive layer of acid load. Cows pant, 00:29:00.250 --> 00:29:02.849 they hyperventilate, and they lose bicarbonate, 00:29:02.910 --> 00:29:04.730 which is their natural systemic buffer. This 00:29:04.730 --> 00:29:07.210 makes the rumen far more fragile. So they need 00:29:07.210 --> 00:29:09.670 to focus intensely on feeding during cooler times, 00:29:09.890 --> 00:29:12.809 ensuring aggressive, effective cooling, and using 00:29:12.809 --> 00:29:15.289 yeast and buffer strategically as part of a total 00:29:15.289 --> 00:29:17.869 heat stress mitigation package, not just standalone 00:29:17.869 --> 00:29:21.039 solutions. Their phase one consistency is paramount 00:29:21.039 --> 00:29:23.660 because a tired, heat -stressed cow is far more 00:29:23.660 --> 00:29:26.140 prone to slug feeding when she finally gets comfortable. 00:29:26.380 --> 00:29:29.019 In every single system, the ultimate goal is 00:29:29.019 --> 00:29:31.660 the same. Prioritize one or two foundational 00:29:31.660 --> 00:29:34.240 changes that you know you can sustain consistently 00:29:34.240 --> 00:29:36.619 because consistency is the currency the rumen 00:29:36.619 --> 00:29:38.819 microbiome trades in. Okay, let's nail down the 00:29:38.819 --> 00:29:42.960 money. We promised the $700 per cow is achievable, 00:29:43.180 --> 00:29:46.359 but we need to show exactly how those gains stack 00:29:46.359 --> 00:29:49.309 up realistically for the producer. Let's use 00:29:49.309 --> 00:29:52.349 that standard thousand cow herd producing around 00:29:52.349 --> 00:29:55.789 85 pounds of milk with a stable milk price of 00:29:55.789 --> 00:29:58.369 roughly 40 cents per kilogram. We are going to 00:29:58.369 --> 00:30:01.109 model the stacked return on investment for operational 00:30:01.109 --> 00:30:04.250 discipline. This is not guesswork. This is based 00:30:04.250 --> 00:30:06.269 on recovering the losses that are cited in the 00:30:06.269 --> 00:30:10.089 research. Let's start with phase one gain. Timing 00:30:10.089 --> 00:30:12.670 and access. If tightening up your feed access 00:30:12.670 --> 00:30:15.849 eliminates those chronic 10 -hour overnight gaps 00:30:15.849 --> 00:30:19.250 and you recover just a conservative 0 .75 to 00:30:19.250 --> 00:30:22.369 0 .8 kilograms of milk per cow per day. Which 00:30:22.369 --> 00:30:25.450 is less than half of the 7 .9 -pound Penn State 00:30:25.450 --> 00:30:28.049 reported loss, just to be conservative. Right. 00:30:28.089 --> 00:30:30.569 That's an income increase of about 30 to 35 cents 00:30:30.569 --> 00:30:33.380 per cow per day. Multiplied over a thousand cows 00:30:33.380 --> 00:30:37.059 for 365 days, that single low -cost operational 00:30:37.059 --> 00:30:40.579 change nets you between $110 ,000 and $120 ,000 00:30:40.579 --> 00:30:43.779 in additional immediate milk revenue. That easily 00:30:43.779 --> 00:30:46.359 pays for a high -end feed pusher or a dedicated 00:30:46.359 --> 00:30:49.119 night push -up labor contractor in under a year. 00:30:49.240 --> 00:30:51.980 That's pure profit unlocked by just managing 00:30:51.980 --> 00:30:55.460 a schedule. Next. Phase two gain, sorting and 00:30:55.460 --> 00:30:58.220 particle size. If getting the physical structure 00:30:58.220 --> 00:31:00.700 of the TMR under control prevents sorting and 00:31:00.700 --> 00:31:02.960 helps you recover the five to six pounds of DMI 00:31:02.960 --> 00:31:06.039 lost to overly long particles, that can translate 00:31:06.039 --> 00:31:10.119 to another 1 .3 to 1 .4 kilograms of milk per 00:31:10.119 --> 00:31:13.539 cow per day. Plus, and this is critical, you 00:31:13.539 --> 00:31:16.059 get a component pump because the rumen is healthier 00:31:16.059 --> 00:31:18.119 and it's producing more acetate for butterfat. 00:31:18.490 --> 00:31:21.130 That easily translates into another $200 ,000 00:31:21.130 --> 00:31:24.309 to $250 ,000 annually in combined volume and 00:31:24.309 --> 00:31:26.789 component pay. You stabilize your butterfat, 00:31:26.910 --> 00:31:28.329 which is often the difference between hitting 00:31:28.329 --> 00:31:30.750 and missing premium component contracts. And 00:31:30.750 --> 00:31:32.869 that's just by adjusting your halage chop and 00:31:32.869 --> 00:31:35.740 your mixer timing. Now phase three gain, DM checks. 00:31:35.960 --> 00:31:38.220 This one is about loss prevention, which is harder 00:31:38.220 --> 00:31:40.299 to quantify, but it's essential for stability. 00:31:40.720 --> 00:31:42.700 Preventing those silent weeks where moisture 00:31:42.700 --> 00:31:45.740 shifts lead to DMI dips, even if you only prevent 00:31:45.740 --> 00:31:48.380 a loss of half a kilo per cow per day across 00:31:48.380 --> 00:31:51.559 10 bad weeks a year. That saves tens of thousands 00:31:51.559 --> 00:31:53.579 in loss production and troubleshooting time. 00:31:53.720 --> 00:31:56.400 You stabilize the system's floor. Finally, the 00:31:56.400 --> 00:31:59.819 cherry on top, phase four additives. If your 00:31:59.819 --> 00:32:02.480 now stable system is working perfectly, and you 00:32:02.480 --> 00:32:04.819 introduce a strategic yeast program into your 00:32:04.819 --> 00:32:07.599 fresh cow pen, and that helps you add another 00:32:07.599 --> 00:32:10.980 0 .7 or 0 .8 kilograms of milk in those highest 00:32:10.980 --> 00:32:14.859 risk animals, you might net $50 ,000 after product 00:32:14.859 --> 00:32:17.619 cost. So when you stack those three operational 00:32:17.619 --> 00:32:20.960 gains and the final fine -tuning, you have mathematically 00:32:20.960 --> 00:32:24.480 justified that $500 ,000 to $700 ,000 upside, 00:32:24.680 --> 00:32:27.599 or $500 ,000 to $700 ,000 per cow. And even if 00:32:27.599 --> 00:32:29.960 you only achieve 60 % of these modeled gains 00:32:29.960 --> 00:32:31.859 because your management was already better than 00:32:31.859 --> 00:32:34.480 average, you are still talking about a six -figure 00:32:34.480 --> 00:32:36.940 swing on a thousand -cow unit just by treating 00:32:36.940 --> 00:32:39.380 the rumen microbiome with operational respect. 00:32:39.740 --> 00:32:42.119 But we have to inject a serious dose of skepticism 00:32:42.119 --> 00:32:44.319 here. This is not a guaranteed win. Where do 00:32:44.319 --> 00:32:46.200 these well -intentioned efforts usually go off 00:32:46.200 --> 00:32:48.660 the track? The single biggest failure point is 00:32:48.660 --> 00:32:50.759 what we call the acidosis paradox, or partial 00:32:50.759 --> 00:32:53.940 implementation. A farmer hears this deep dive, 00:32:54.140 --> 00:32:56.259 gets excited about phase one, and tightens up 00:32:56.259 --> 00:32:58.579 the timing so cows get continuous feed access. 00:32:59.099 --> 00:33:02.660 But they fail to fix phase two. They still have 00:33:02.660 --> 00:33:05.099 a highly sortable ration with excessive long 00:33:05.099 --> 00:33:07.740 particles. Wait, so if they start eating more 00:33:07.740 --> 00:33:10.299 often, but the ration is sortable, they eat more 00:33:10.299 --> 00:33:12.960 of the wrong stuff more consistently. Exactly. 00:33:12.960 --> 00:33:15.259 They flood the rumen with starch more frequently 00:33:15.259 --> 00:33:17.579 because they are no longer restricted. You can 00:33:17.579 --> 00:33:19.740 actually increase the incidence and severity 00:33:19.740 --> 00:33:22.619 of acidosis by only fixing phase one. That's 00:33:22.619 --> 00:33:24.980 a crucial warning. You have to nail phase two 00:33:24.980 --> 00:33:27.839 immediately after phase one or you might make 00:33:27.839 --> 00:33:30.339 things worse. Another pitfall we see constantly 00:33:30.339 --> 00:33:33.680 on large dairies is labor overestimation. You 00:33:33.680 --> 00:33:35.779 can design a perfect plan that requires seven 00:33:35.779 --> 00:33:38.220 push -ups a day, but if you don't have the reliable 00:33:38.220 --> 00:33:40.599 staff or if the staff isn't trained and motivated, 00:33:40.819 --> 00:33:43.039 that plan is going to revert back to the drift 00:33:43.039 --> 00:33:45.200 within two months. You have to implement high 00:33:45.200 --> 00:33:47.759 -impact, low -labor, and sustainable changes. 00:33:48.079 --> 00:33:51.319 Better one automated push -up than three unreliable 00:33:51.319 --> 00:33:54.000 human ones. And, we can't stress this enough, 00:33:54.279 --> 00:33:57.759 the additive expectation. Yeast and buffers cannot 00:33:57.759 --> 00:34:01.000 solve structural issues like poor forage quality, 00:34:01.299 --> 00:34:04.519 excessive stocking density, or fresh cow limits 00:34:04.519 --> 00:34:07.680 due to facility design. If the structural bottlenecks 00:34:07.680 --> 00:34:10.920 exist, the money spent on additives is just wasted 00:34:10.920 --> 00:34:14.460 on chasing a symptom, not fixing the cause. Address 00:34:14.460 --> 00:34:16.900 the fundamentals first. So what does this foundational 00:34:16.900 --> 00:34:19.599 management mean for the long game? Why should 00:34:19.599 --> 00:34:22.239 producers focus on this now, even if their margins 00:34:22.239 --> 00:34:24.070 are tight? Because they are setting themselves 00:34:24.070 --> 00:34:26.449 up for the next generation of performance metrics. 00:34:26.929 --> 00:34:29.469 Future trends in breeding proofs are focusing 00:34:29.469 --> 00:34:31.730 more and more heavily on actual feed efficiency, 00:34:32.070 --> 00:34:35.289 on RFI, and on methane output. And we know the 00:34:35.289 --> 00:34:38.269 cow's microbiome is responsible for 36 % of RFI 00:34:38.269 --> 00:34:41.010 variation, and it's also the key driver in methane 00:34:41.010 --> 00:34:43.659 production. Exactly. Processors and sustainability 00:34:43.659 --> 00:34:46.320 programs are inevitably going to start monitoring 00:34:46.320 --> 00:34:49.400 feed conversion ratios more closely. If you already 00:34:49.400 --> 00:34:51.800 have the operational systems in place to maximize 00:34:51.800 --> 00:34:54.559 DMI consistency and minimize sorting, you are 00:34:54.559 --> 00:34:56.559 far better positioned for the next 10 years. 00:34:56.800 --> 00:34:59.360 Efficiency is going to become even more valuable 00:34:59.360 --> 00:35:01.699 than total output. It's not just about producing 00:35:01.699 --> 00:35:03.860 more milk. It's making sure that every single 00:35:03.860 --> 00:35:06.420 pound of feed is utilized, not just delivered. 00:35:06.659 --> 00:35:09.260 And that comes down to managing the microbial 00:35:09.260 --> 00:35:11.539 environment. Which in turn means managing your 00:35:11.539 --> 00:35:14.260 labor, your schedule, and your mixer wagon discipline. 00:35:14.719 --> 00:35:17.059 Precisely. All right. We've covered the science, 00:35:17.139 --> 00:35:19.739 the operational failures, and the massive financial 00:35:19.739 --> 00:35:22.480 opportunity. A farmer just finished milking. 00:35:22.829 --> 00:35:25.210 and is driving to the feed store right now thinking 00:35:25.210 --> 00:35:29.030 about that $700 per cow, what are the three non 00:35:29.030 --> 00:35:31.090 -negotiable things they need to remember from 00:35:31.090 --> 00:35:33.550 today? We need to connect the action directly 00:35:33.550 --> 00:35:36.190 to the financial reward. Three things. Let's 00:35:36.190 --> 00:35:37.929 make this the implementation guide to room and 00:35:37.929 --> 00:35:41.989 gold. Number one, eliminate the 7 .9 pound milk 00:35:41.989 --> 00:35:45.309 thief. Master phase one timing. Immediate action 00:35:45.309 --> 00:35:48.469 this week. Put a camera or a notepad in the feed 00:35:48.469 --> 00:35:50.929 room. Log actual feed delivery and push -up times 00:35:50.929 --> 00:35:53.030 for all high -producing groups for seven days 00:35:53.030 --> 00:35:55.570 straight, including the weekends. Identify every 00:35:55.570 --> 00:35:57.650 recurring feed gap that is longer than the three 00:35:57.650 --> 00:35:59.889 -hour maximum. Be honest about that overnight 00:35:59.889 --> 00:36:02.530 window. Medium -term strategy, three to six months. 00:36:03.030 --> 00:36:06.250 Implement one sustained, reliable, change -like 00:36:06.250 --> 00:36:09.469 adjusting crew handoffs or scheduling a dedicated 00:36:09.469 --> 00:36:12.110 late -night check to eliminate the single longest 00:36:12.110 --> 00:36:14.889 feed restriction gap. That's the Saturday morning 00:36:14.889 --> 00:36:18.480 problem. Recovering a conservative 0 .75 kilograms 00:36:18.480 --> 00:36:21.500 of milk per cow per day in this phase is your 00:36:21.500 --> 00:36:24.039 immediate goal. Long -term positioning, one to 00:36:24.039 --> 00:36:27.000 two years. Analyze the ROI of simple technology 00:36:27.000 --> 00:36:29.519 like automatic pushers or feed timing alerts. 00:36:29.760 --> 00:36:31.920 You have to view this capital investment as non 00:36:31.920 --> 00:36:34.340 -negotiable insurance to guarantee continuous 00:36:34.340 --> 00:36:37.860 feed access and prevent that systemic 7 .9 pound 00:36:37.860 --> 00:36:40.639 milk loss that just erodes stability. Okay, number 00:36:40.639 --> 00:36:43.400 two. Audit the Eaton Ration Daily, Master Phase 00:36:43.400 --> 00:36:46.059 2 and 3 consistency. Immediate action this week. 00:36:46.239 --> 00:36:49.019 Spend 45 to 60 minutes standing at the bunk immediately 00:36:49.019 --> 00:36:51.199 after feeding high -producing pens. Watch them 00:36:51.199 --> 00:36:54.039 sort. Next, add one weekly TMR dry matter check 00:36:54.039 --> 00:36:56.500 using a coaster or a microwave, especially when 00:36:56.500 --> 00:36:58.460 starting a new bunker section or after a heavy 00:36:58.460 --> 00:37:01.380 rain. Medium -term strategy, three to six months. 00:37:01.539 --> 00:37:04.340 Run the PSPS weekly for a month to get a quantifiable 00:37:04.340 --> 00:37:06.820 baseline on your TMR particle size and refusal 00:37:06.820 --> 00:37:09.239 sorting. Work with your nutritionist to adjust 00:37:09.239 --> 00:37:12.139 chop length or mixing time until the ration meets 00:37:12.139 --> 00:37:15.360 those specific PSPS targets, especially that 00:37:15.360 --> 00:37:17.539 two to eight percent on the top sieve to make 00:37:17.539 --> 00:37:19.579 the feed non -sortable. Long -term positioning, 00:37:19.780 --> 00:37:23.050 one, two years. Formalize a simple trigger. the 00:37:23.050 --> 00:37:25.369 two -point DM swing that automatically prompts 00:37:25.369 --> 00:37:27.429 immediate batch weight adjustments by the feeder. 00:37:27.750 --> 00:37:30.929 Establish DM checks and PSPS analysis as standard, 00:37:31.010 --> 00:37:33.869 non -negotiable routine management, turning consistency 00:37:33.869 --> 00:37:36.570 into a systematic operation. And finally, number 00:37:36.570 --> 00:37:39.750 three, unlock genetic potential, phase four fine 00:37:39.750 --> 00:37:42.320 -tuning. Immediate action this week. Use your 00:37:42.320 --> 00:37:44.780 existing herd data, your fat -to -protein ratios, 00:37:45.079 --> 00:37:47.679 ruination indices, manure scores, as an early 00:37:47.679 --> 00:37:50.340 warning signal for microbial instability. Don't 00:37:50.340 --> 00:37:52.480 wait for the bulk tank to drop. Use these leading 00:37:52.480 --> 00:37:54.079 indicators to trigger management adjustments. 00:37:56.969 --> 00:37:59.570 only after phase one two and three are demonstrably 00:37:59.570 --> 00:38:02.329 solid then you discuss a focused trial with live 00:38:02.329 --> 00:38:04.809 yeast or buffers with your nutritionist target 00:38:04.809 --> 00:38:07.349 specific high return groups like transition cows 00:38:07.349 --> 00:38:10.489 or fresh cows to maximize the one to two kilogram 00:38:10.489 --> 00:38:13.230 per day yield potential those products offer 00:38:13.230 --> 00:38:16.269 when used correctly long -term positioning one 00:38:16.269 --> 00:38:19.329 to two years. View all operational labor and 00:38:19.329 --> 00:38:22.010 capital investments in timing and TMR consistency 00:38:22.010 --> 00:38:25.530 as foundational expenditures. These investments 00:38:25.530 --> 00:38:27.510 are what ultimately unlock the full expression 00:38:27.510 --> 00:38:29.710 of your expensive genetics and strategic feed 00:38:29.710 --> 00:38:33.110 additives, capturing the total 500 to $700 per 00:38:33.110 --> 00:38:35.489 cow margin that's currently hiding in your daily 00:38:35.489 --> 00:38:37.989 routine.
